Hi,
Just wanted to express my thanks to pionara and radeonorama for making this available. I successfully updated my UK AVIC-F9210BT, using a cheap Tanscend 4GB SDHC card I bought from Maplin. It took around 25 minutes for the main update and 5 minutes for the Bluetooth update. I did the tweak to the VERINFO.DAT file too.
You don't often find a full and easy to follow solution to this type of thing on the web so how easy this was, was very refreshing.
Cheers,
Paul
